Sombra, a Colombian sniffer dog, has taken part in operations leading to 245 arrests, and has found millions of dollars worth of cocaine.

In the last three years she has become the "torment" of the Urabeños gang, and had located nine tonnes of their cocaine, police say.

Now the Urabeños have put a bounty of 200 million pesos ($70,000) on her head, according to the head of the national police.

The dog has been moved to the airport for her safety, where she will continue to sniff out drugs.

A police dog in Colombia that has sniffed out a record amount of drugs had to be relocated and given police protection after a gang put a $70,000 bounty on her head, according to the national police.

Sombra, German Shepherd, has taken part in operations leading to the arrest of at least 245 suspected drug runners, and has found a total of nine tonnes of cocaine, which could otherwise have been sold for more than $200 million.

General Jorge Nieto, the director general of Colombia's national police, wrote this message on Twitter praising Sombra's efforts:

The gang is now offering 200 million in pesos, the local currency, for her life, Nieto wrote. It's worth around $70,000.

The gang, also known as El Clan del Golfo, (The Gulf's Clan) was born from the country's paramilitary movement.

Sombra (whose name means "shadow") has been moved to the El Dorado airport in Bogotá, Colombia's capital, for her own safety.

She has been with Colombian police for six years, and in the last three became the "torment" of the gang, the police's official anti-narcotics force wrote on Twitter.

The force wrote that Sombra had been the "best" during her training in illicit drug protection, and also encouraged travelers to take selfies with her at the airport where she "protects the lives of children and adolescents from the deadly poison of drugs."
